First Look! Ali Lohan Strikes a Pose for First Non-Lindsay-Related Campaign

Lindsay Lohan's 17-year-old sis—we used to know her as Ali, but she's out there on Twitter now as "Aliana T. Lohan, Model"—is the new face of designer denim line PRVCY Premium, and E! News has obtained an exclusive sneak peek at its spring/summer 2012 relaunch campaign.

While news that Ali (we're going to just keep going with her cute, little-sis nickname) had signed with NEXT Model Management seemed a little random, the used-to-being-photographed teen made her aspirations known when she starred in the spring-summer 2011 ad campaign for Lindsay's 6126 line.

For PRVCY, however, Ali is dolled up in the truer sense of the word. The makeup's more natural, the clothes are more age-appropriate and, happily, the underwear isn't showing.

And the kid is loving every minute of it.

"I was thrilled to model for PRVCY Denim, everyone was amazing to work with," Ali exclusively tells E! News. "The collection has the best fit and I love the styling for this upcoming season."

"I am confident that Ali will further the label's coveted reputation and help reintroduce the brand to our targeted demographic," added Christian Wicks, president of the Apparel and Accessories Division of PRVCY parent Omni Ventures.

"We believe that Ali has immense potential and is a perfect fit for the PRVCY family."
